Step-by-step roadmap

  1. Start

    You will finish with: response plots and a justified damping value.

  2. 1

    Prerequisites

    Nothing special to know first. Then collect the 1 item in the materials list.

  3. 2

    Learn

    Read up on vehicle dynamics: damping, suspension, vibration. Your textbook chapter and one short video are enough.

  4. 3

    Plan

    List the features for version one, sketch the screens or data flow and pick the tools. Keep the first version small.

  5. 4

    Build

    1. Write the equations for a quarter-car with a spring and damper.
    2. Simulate driving over a step bump.
    3. Plot body displacement and acceleration.
    4. Vary the damping and compare.
    5. Choose the value that balances comfort and control.
  6. 5

    Test

    Try it with wrong, empty and unusual input, and ask someone else to use it without your help.

  7. 6

    Document

    Write a README: what it does, how to run it, screenshots and what you learned. Report structure

  8. 7

    Present

    Show a live demo of one complete task, then the design and the hardest problem you solved. Presentation structure

  9. 8

    Publish

    Put the code on GitHub with the README and, if you can, deploy a live demo.

Expected outcome

Response plots and a justified damping value.

Other versions of this project

Advanced version

Add tyre stiffness as a second mass and compare.

Ways to do this project

Text marked "You write this" is a prompt for your own work; everything else is specific to this project.

Research question
You write thisOne question you can answer with data, narrow enough to finish in the time you have.
Hypothesis
You write thisWhat you expect to find, and why.
Variables
You write thisWhat you change or compare, what you measure, and what you hold constant.
Methodology
You write thisDescribe the method in enough detail that someone else could repeat it: sample, tools, procedure.
Data collection
You write thisSay what you will record, how many times, and how you will keep the records safe.
Analysis
You write thisChoose the table, chart or test that answers the question; report averages with their spread.
Limitations
You write thisList what could have affected the result: small sample, instrument limits, things you could not control.

Literature review

Find five to eight sources (your textbook, review articles, reports) and note what each says about your question. Group them by idea, not one after another, and end with what is still not known.

References

List every source you used in one style throughout (author, year, title, where it was published, link and the date you opened it).

Viva questions

Prepare your own answers to these before you present.

  • What is the aim of your project, in one sentence?
  • What is the principle behind it?
